Definitions

  • the invention relates to a coupling device, comprised of two connector block parts that can be coupled to each other with a plurality of receivers for connector parts.
  • the connector parts are arranged corresponding with each other and can be connected to each other.
  • Coupling devices of this type belong to the prior art and are known as multiple media couplings or multiple couplings.
  • DE 10 2009 030 936 A1 describes a coupling device of this type.
  • These coupling devices can have a larger number of connector parts, which can be plugged together for connecting line sections.
  • These lines can be for flowable media, like compressed air, or can be electrical lines.
  • a secure mutual sealing of the connector parts by a sealant is essential in the coupling state.
  • a higher exertion of force can be required for carrying out the coupling process due to the friction on the sealants and because of the media pressure counteracting the connection.
  • the invention addresses the problem of providing a coupling device of the type specified in the introduction that facilitates a simple and comfortable implementation of the coupling process, even in the case of a greater number of connector parts.
  • a coupling device having, as one essential special feature of the invention, a facilitating device, for facilitating the coupling process, having a pivotable handle with at least one guide slot on the one connector block part. At least one guide part of the other connector block part engages in the guide slot such that, when the handle is pivoted the guide slot applies a force to the guide part causing the connector block parts to be moved toward each other for a coupling process.
  • a high force component acting in axial direction can be generated via the guide slot on the guide part engaging in it with a low amount of pivot torque to be applied to the handle by the operator.
  • the pivotable handle encompasses the assignable connector block part in the manner of a bracket and has two side parts.
  • the side parts of this connector block part which are parallel and opposite each other, are pivotably arranged on the connector block part.
  • Each side part has a guide slot extending parallel to each other, penetrating the respective side part in areas, and arranged in the respective side part.
  • the actuating part of the handle can be formed by a cross-member extending between the two side parts.
  • the actuation a grip part may then be formed by the cross-member with sufficient length in relation to the width of the bracket and can be grasped particularly conveniently.
  • the respective guide part of the other connector block part can be formed by a guide pin.
  • Two guide pins are arranged in pairs and in the same engagement position at side walls of the other connector block part.
  • the two pins are arranged opposite such that they lie in the pivot path of the respective assignable guide slots when the connector block parts approach each other toward their coupling position.
  • the bracket design so arranged, the risk of jamming when bringing the connector block parts together is avoided, because, in the case of axial force generated simultaneously on opposing sides of the other connector block part, the connector block parts are brought together without diagonal pull.
  • the assembly can be made such that the side parts with the guide slot are configured as a pivoting fork and connected to each other in pairs on one end via a plate-shaped or rod-shaped grip part.
  • the guide slot on the opposing end of the respective side part for receiving the guide pin of the other connector block part opens outward.
  • the guide path of the guide slot has a curved shape at least in the region of the opening and proceeding from it.
  • the assembly can be made such that, at least on one pivot axis on the one connector block part, the pivotable side part remains positioned in a force-locking manner by a pretensioning device, preferably in the form of at least one yoke spring, in every pivotal position.
  • a pretensioning device preferably in the form of at least one yoke spring
  • the connector block parts can be configured as round bodies or as cuboids in a type of box design.
  • FIG. 1 is a perspective view of a coupling device according to a first exemplary embodiment of the invention in the incompletely coupled state;
  • FIG. 2 is a perspective view of the coupling device of FIG. 1 in the completely coupled state
  • FIG. 3 is an exploded, perspective view of a coupling device according to a second exemplary embodiment of the invention.
  • FIG. 4 is an exploded, side view of the coupling device of FIG. 3 .
  • the coupling device forms on the whole a round or cylindrical element.
  • the first connector block part 2 which is visible at the front in FIGS. 1 and 2 , is designed in the manner of a coupling socket.
  • a shell part 6 of the second connector block part 4 which is reduced in its external diameter, can be inserted into the first connector block 2 when the device is transferred from the incompletely coupled state shown in FIG. 1 to the completely coupled state shown in FIG. 2 .
  • receivers are aligned perfectly to each other, which receivers are provided in connector block parts 2 and 4 for connector parts affixed to the ends of line sections to be connected to each other.
  • FIGS. 1 and 2 four receivers 8 are provided for connector parts 10 .
  • three of the receivers 8 have been left empty, and only one inserted connector part 10 is visible, which is shown without an associated line section.
  • the connector parts 10 of the one connector block part 2 have been brought together with the connector parts 10 of the second connector block part 4 , wherein a sealant forms the seal between the connector parts 10 .
  • the second connector block part 4 is extended by an attachment 12 , which extends with slightly conical taper to a line guide part 14 , which forms the exit for a relevant bundle of lines (not shown) in the figure.
  • a facilitating device which facilitates the carrying out of the coupling process for the operator, has a handle bracket 16 .
  • the handle bracket is designed in the form of a pivot arm, which has two identically configured side parts 18 in the form of sheet metal plates.
  • Each side part 18 has one end 20 on one of the two opposing sides of the first connector block part 2 .
  • Each end 20 is pivotably mounted on a pivot pin 22 around a pivot axis.
  • the side parts 18 are connected to each other by a round bar 26 forming a grip part or handle.
  • the side parts 18 In the area between the ends 20 and 24 , the side parts 18 each have an extension 28 protruding towards the second connector block part 4 , in which a slot 30 is formed.
  • Each slot 30 forms a guide slot and is open in the region of the end of the extension 28 .
  • the guide slots formed by the slots 30 of the side parts 18 serve as control elements for guide pints 32 .
  • the control elements or guide pins 32 project coaxially on opposing sides of the second connector block part 4 .
  • the guide pins 32 proceeding from the state shown in FIG. 1 upon pivoting the handle 16 clockwise, enter into the slots 30 from their open ends.
  • the slots 30 proceeding from their openings, are curved in the shape of a bow.
  • the guide pins 32 move along the slots 30 .
  • a force component then develops on the guide pins 32 in axial direction, pulling the connector block parts 2 and 4 against each other, so that the coupling device reaches the coupling state.
  • a pivot actuation of the handle 16 can be comfortably performed with low actuating force resulting in a high axial force for a secure coupling process.
  • FIGS. 3 and 4 show a second exemplary embodiment.
  • the first and second connector block parts 2 and 4 are not formed by round or cylindrical bodies, but rather in the manner of a box design in the form of cuboids.
  • the receivers 8 for the respective connector parts 10 are located in the connector block parts 2 , 4 .
  • the connector parts 10 are for electrical line sections (not shown).
  • one guide rod 36 each is provided on the first connector block part 2 near each short side of the rectangular shape. The guide rods 36 engage in guide bores (not visible in the figure) in the second connector block part 4 in the coupling process.
  • the facilitating device facilitating the coupling process is in formed in a corresponding manner by a handle 16 in a bracket design with the side parts 18 configured the same as described in the first exemplary embodiment.
  • the grip part 26 connecting the ends 24 of the side parts 18 is formed not by a round bar, but rather is formed by a cross-member in one piece with the side parts 18 .
  • protruding guide pins 32 are provided for the interaction with the guide slots formed by the slots 30 of the side parts 18 on both sides of the second connector block part 4 .
  • each slot-shaped guide slot 30 has a recess or bulge 51 on the rear end protruding towards the grip part. Each bulge 51 is to be bridged and locks the bracket in the form of the handle 16 , so that in the coupled state it is secured against unintentional loosening without third party interference. The force is applied to seal over the distance to be bridged.
  • the second exemplary embodiment has pivot bearings with screws 38 in place of the pivot pins 22 , with which yoke springs 40 are held.
  • Each yoke spring 40 is in contact with the exterior of the relevant side part 18 under a pre-tensioning force.
  • the handle 16 is secured in a force-locking manner against unwanted pivoting movements as a result, when the connector block parts 2 and 4 are not coupled and the handle 16 is therefore free.
  • a guide bracket 42 is provided as the guide for a bundle of lines extending away from the second connector block part 4 .
  • the bundle of lines (not shown in the figure) is in place of the attachment 12 provided in the first exemplary embodiment with exit guide part 14 .
